Britney Spears had a concert in Vancouver this week and apparently the diva put the concert on hold just after lip singing three songs. The reason she did that was because there was too much smoke in the arena.
We know Britney is a smoker herself but the problem wasn’t the cigarette smoke, was the smoke created by those that smoked weed.
It seems Britney didn’t wanted to have any trouble with her drug tests regarding her children custody and being in a place where it’s a lot of weed smoke she could have inhale that and the test would have said she is on drugs now. That’s a smart move I might say.

After 20 minutes of break Britney got back on stage and at the end of the show she said to the audience Thanks Vancouver. You were wonderful. Drive safe. Don’t smoke weed! (via)
